Constraint propagation algorithms for the car sequencing problem
Matthießen, Lars; Drexl, Andreas; Kimms, Alf - 2000
The car sequencing problem is to find feasible sequences of product variants requiring specific options while taking care of sequencing constraints. First, a branching scheme and constraint propagation algorithms for the computation of feasible sequences are provided. Second, an algorithm is...

Belastungsorientierte Just-in-Time Variantenfließfertigung
Drexl, Andreas; Kimms, Alf - 1999
Gegenstand der vorliegenden Arbeit sind zwei praktisch und theoretisch bedeutsame Probleme, die bei just-in-time orientierter Variantenfließfertigung auftreten. Ein Problem besteht darin, den Teilebedarf in der Endmontage so konstant wie möglich zu halten ("Level Scheduling Problem"). Das...

Simulating Tail Probabilities in GI/GI.1 Queues and Insurance Risk Processes with Subexponentail Distributions
Boots, Nam Kyoo; Shahabuddin, Perwez - 2001

Sequential-analysis-based randomized-regret-methods for lotsizing and scheduling
Drexl, Andreas; Haase, Knut - 1993
Lotsizing and scheduling comprises activities which have to be done repeatedly within MRP-systems. We consider the proportional (multi-item, capacitated, dynamic) lotsizing and scheduling problem which is more general than the discrete lotsizing and scheduling problem as well as the continuous...

The Shape of the Loss Curve and the Impact of Long-Range Dependence on Network Performance
Mandjes, Michel; Boots, Nam Kyoo - 2001
Empirical studies showed that many types of network traffic exhibit long-range dependence (LRD),i.e., burstiness on a wide variety of time-scales. Given that traffic streams are indeed endowed withLRD properties, a next question is: what is their impact on network performance? To assess...

Fast Simulation of a Queue fed by a Superposition of Many (Heavy-Tailed) Sources
Boots, Nam Kyoo; Mandjes, Michel - 2001

Due to the exponential decay (in n …,the change of measure is not constant during the simulation run, which is essentially differentfrom many other studies (usually … indeedimproves considerably over naive simulation.

Endogeneous household interaction
Del Boca, Daniela; Flinn, Christopher J. - 2009
Most econometric models of intrahousehold behavior assume that household decision-making is efficient, i.e., utility realizations lie on the Pareto frontier. In this paper we investigate this claim by adding a number of participation constraints to the household allocation problem. Short-run...

Optimal redistributive taxation with both extensive and intensive responses
Jacquet, Laurence; Lehmann, Etienne; van der Linden, Bruno - 2010
This paper characterizes optimal income taxation when individuals respond along both the intensive and extensive margins. Individuals are heterogeneous across two dimensions: specifically, their skill and disutility of participation. Preferences over consumption and work effort can differ with...
